Problems solved by technology

The metal case in particular is cumbersome and increases manufacturing cost.
This vertical play gives the user the feeling that the flash memory card is cheap and unreliable, even when sufficient electrical contact is made.

Embodiment Construction

The present invention relates to an improvement in slim USB connectors. The following description is presented to enable one of ordinary skill in the art to make and use the invention as provided in the context of a particular application and its requirements. Various modifications to the preferred embodiment will be apparent to those with skill in the art, and the general principles defined herein may be applied to other embodiments. Therefore, the present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.

FIGS. 5A-E show a slim USB connector with locking depressions, dividers, and end rails. Male slim USB connector 40 does not include a metal case surrounding a connector substrate, allowing the height H (FIG. 5C) and cost of the connector to be reduced. Instead, the width W (FIG. 5D, E) is wider than the standard male USB connector. The ...

Abstract

A slim Universal-Serial-Bus (USB) connector fits on only one side of the connector substrate in a standard female USB connector. Wobble or vertical play is reduced by locking depressions in the slim USB connector that engage metal springs on a metal case that surrounds the female USB connector, locking the two connectors together. Between metal contacts on the slim USM connector are dividers that help fill in gaps when the two connectors are connected together, further reducing play. End rails on the slim USB connector fill in gaps on the sides. The connector substrate of the slim USB connector can be separate or can be integrated with a circuit board that holds a flash memory chip and a USB controller chip. The connector is wider than the standard width for a better fit. A slim female USB connector for use with the slim male USB connector is also disclosed.

Description

BACKGROUND OF INVENTIONThis invention relates to electronic connectors, and more particularly to reduced-height Universal-Serial-Bus (USB) connectors.Rapid advances in technology in several areas have converged to enable small, portable memory cards with vast capacities. Flash memory technologies such as those using electrically-erasable programmable read-only memory (EEPROM) have produced chips storing 128 M-Bytes or more. Small flash-memory cards have been designed that have a connector that can plug into a specialized reader, such as for compact-flash, secure-digital, memory stick, or other standardized formats.More recently, flash memory cards are being sold that contain a USB connector. Such USB-flash memory cards do not require a specialized reader but can be plugged into a USB connector on a personal computer (PC). These USB-flash memory cards can be used in place of floppy disks. A USB-flash card can have a capacity of more than ten floppy disks in an area not much larger th...
